In this post, I like to present the MAX6675 temperature module at Arduino UNO. In the past post at my blog, I show you another digital temperature sensor Arduino Lesson #6 – digital temperature sensor DS18B20, but this sensor is very special. Buy a MAX6675 temperature module You can find this module very cheap at…

Shelly 1 #1 – set up and operate from a power socket
In this post, I want to introduce you to the Shelly and show you how to set it up and create an app-controlled socket. I have already explained in detail how to control a socket using Amazon Alexa in the German article ESP8266 – Alexa gesteuerte Steckdose. Here, however, we will first look at how…
Arduino Lesson #7 – Photoresistor
In this post, I like to show, how to connect and code a Photoresistor at an analog pin on the Arduino. You get the photoresistor as simple electronic part or pre soldered at a tiny pcb. I show you a circuit with both of them. Buy a Photoresistor You can find and buy this tiny…
Arduino Lesson #6 – digital temperature sensor DS18B20
In this post, I like to show how to connect and code a digital temperature sensor DS18B20 at Arduino UNO. I’ve shown you in my last blog post Arduino Lesson #5 – analog temperature sensor LM35DZ an analog temperature sensor. Here you get some information how to connect the digital sensor DS18B20. Required components for…
Arduino Lesson #5 – analog temperature sensor LM35DZ
In this new post at my technic-blog, I like to show, how to read temperature values from an analog LM35DZ device at Arduino UNO. Buy a LM35DZ sensor for Arduino The analog temperature sensor of type LM35DZ is very cheap, and you get this device at ebay.de for €1.7 without shipping cost*. If you want…
Arduino Lesson #4 – programming IR Remote control
In this new post at my technic blog, I like to show you how to code an IR Remote control at Arduino UNO R3. In my last post Arduino Lesson #3 – control tiny servo motor SG90 I show you how to code and control a servo motor. In this post, I want to control…
Arduino Lesson #3 – control tiny servo motor SG90
In this post, I like to show, how to control a tiny servo motor like the SG90 with an Arduino UNO. Required components for circuit To rebuild the circuit, you need: Types of servo motors At the market, you can find some different types of servo motors. The main different is the weight and power…
Arduino Lesson #2 – LED flashing, traffic light
In this new post, I like to show how to flash a LED at Arduino, and later I would like to show a small traffic light. In my last post Arduino Lesson #1 – setup & install Arduino IDE I have shown you how to setup and install the required tool Arduino IDE 2.0. If…
